Recently, Huawei held the inaugural meeting of the Legion of Honor, announcing the formal establishment of the Coal Mining Legion, starting from the coal mine into the intelligent mining industry, so that the coal mine and even the mining industry has a real absolute safety. Why Huawei "mining", relying on the most advanced F5G technology, will bring us what disruptive changes in the mining industry?
One Why is coal mine safety so important?
Coal mining is mostly underground hundreds of meters or even thousands of meters deep tunnels and working faces, coal mines are not to not have accidents, an accident is a big accident, coal mine safety has been doubly concerned by all sectors of society. In recent years, China's successive major coal mine safety production accidents, resulting in serious casualties and major property losses, a number of relevant government officials due to be accountable. National Energy Administration data, as of the end of 2020, the number of coal mines in the country 4,700, raw coal production of 3.9 billion tons, 122 fatal accidents in 2020, 225 deaths.
Between 2010 and 2020, the proportion of coal in China's primary energy consumption structure fell from 69.2% to 56.8%, but still accounted for more than half. Although the National Energy Administration (NEA) is gradually reducing the number of coal mines, coal will remain China's main source of energy in the coming decades, and coal mine safety remains a top priority!
Two Coal mines are difficult in terms of safety and succession
Compared to other types of mines, the geological conditions of coal mines are more severe, prone to accidents such as landslides, water penetration, gas explosions and other accidents, and the working environment is high-temperature, high-humidity, high dust; the working face of the mining is up to 200-300 meters long. The working environment is high temperature, humidity, high dust; the mining face is 200-300 meters long, and the site conditions are extremely complex, with high uncertainty and high risk factor;
The biggest challenge in the industry is the safety issue, which is firstly the issue of the safety structure, the issue of the management regulations, and behind it is the issue of the personnel's operation norms, which must be solved by platform and digital means.
First, the lack of unified industry standards: The lack of unified information technology, intelligent construction of standard guidance, the information system between the
The most important thing is the lack of unified industry standards. cannot be interconnected and evolution is difficult.
Secondly, the various production equipment interface is not unified, seven countries and eight systems : IT applications and OT equipment system varied, cross-system integration complexity, IT and OT difficult to integrate, production data can not be or not a unified format, the massive OT equipment data can not be analyzed through IT means and modeling, seriously affecting the value of the data to play.
Third, the lack of a unified operating system: A domestic, independently controlled Internet of Things operating system is needed to realize the definition of a unified format and interface for data, and to create a unified standard and architecture for the access layer of coal mine equipment. Following the subsequent data **** enjoyment, application deployment to lay a solid digital base foundation.
Fourth, data silos: Chimney-style system construction, independent deployment and high maintenance costs, and seriously constrain the flow of data and collaborative applications.
Fifth, no one else: The coal mining industry has a very pressing real-world problem, and that is the embarrassing situation of no one else being able to work in the mines. Currently, miners are generally older than 45 years old, and young people would rather be a courier, even if they have a high income, they don't want to be engaged in such a hard and dangerous occupation. If we can help the industry to realize remote mining, wearing a suit and tie in the office operation, the situation will be different.
Three Why did Huawei mine coal in the first place?
Why did Huawei choose to start with the coal mines? Can't you spread out and do the whole mining development?
Ren Zhengfei said publicly that Huawei applies information and communication technology to mines, most notably to help coal mines achieve intelligence. He said, for example, the current Shanxi underground gas warning explosion-proof system is doing very well, but to use four wires to connect, which has two power lines, two signal lines. When Huawei technology is applied to the underground, the gas sensor no longer needs a line, upward transmission with radio, not only in the pit can be arbitrarily arranged, but also with the miner to move forward arbitrarily, do not need to be because of the wiring caused by the miner's mining movement progress slows down, thus improving the output capacity.
It is understood that the current first to do the coal mine, which is a rigid internal requirements. Why? Huawei does things emphasize a method called saturation attack, determine the strategy, then focus on breaking through a "wall mouth". The "mouth of the wall" for mine development is the coal mine. The coal mine scenario is also the most complex and challenging. If the most demanding coal mine scenarios can be done well, then Huawei has built a leading solution that has withstood severe scenarios, and it will be easier to replicate and apply it to other mining fields.
In 5G and other communications technology, cloud computing, big data technology applications, most of the world's information and communications companies have not chosen to mine as a breakthrough, but Huawei chose to mine the first to eat crabs, and it is ready to use 30 years of accumulation to change the industry. In mine development, coal mine is the most difficult, Ren Zhengfei said, China's existing more than 4,700 coal mines, if you can do a good job of these coal mines, the experience accumulated in the field of coal mining, it is easy to spill over to other non-coal mines.
"If we really realize this step, it will be very significant for Canada and Russia in the Arctic Ocean region of mining. The conditions in the tundra are extremely harsh, people don't want to live there, and with such abundant resources sleeping there, it would be a major contribution to human society if unmanned ways were mined and those resources were extracted."
Four What changes can Huawei bring to the mining industry?
It's the combination of advantages offered by F5G that will underpin the future of smart mining. In that smart underground world, coal mines will have true and absolute safety. Zou Zhilei, Chairman of Huawei Coal Mining Corps, said that Huawei does not do coal digging machines, do not do sensors, do not do application software, but focus on ICT infrastructure, by opening up the information flow of all links in the coal mine, to realize unmanned and intelligent, so that "digging and selling coal do not see coal".

4 applications
① Remote control of equipment
Utilizing the characteristics of 5G high speed, low latency, high connectivity, and high reliability, the remote control of equipment can be achieved by using 5G. connectivity, high reliability and other characteristics, remote super control digging machine, so that the underground inspection and security machine, so that mining unmanned, especially mining can be wearing a suit to sit in a comfortable control room digging, to achieve the coal mine fixed place unattended, the key link robot replacement, help realize intelligent mining, reduce manpower by 60%, reduce the number of people in a single shift by 10% -20%.
Remote control mining to solve the safety of workers and the working environment, now young people are not willing to work in the mines, mine recruitment is a big problem. Most miners are in their 50s and 60s, and young personnel are reluctant to work in mines. Why the current 5G mine can recruit college students, because he only need to sit in the air-conditioned room to operate the excavator can be, so to solve the problem of mining recruitment difficulties.
② Pure electric mine car
Pure electric mine car one is uphill empty car with electricity, downhill reverse charging, downhill energy recovery; two is downhill motor counterbrake is more effective than the brake pads; three is the downhill power consumption is only diesel 1/5, saving 4/5, safety, energy saving and environmental protection, the benefits of a huge; four is not afraid of the special road conditions. Attendance rate is high; Fifth, high reliability and less maintenance.
Henan Luoyang molybdenum mining area has 270 transport vehicles, ore, slag transportation, of which there are 130 sets of pure electric unmanned mine card, 2020 transformation into an unmanned mine extraction capacity of 20 million tons.
③ Driverless and scheduling system
Driverless application in the mining industry has two advantages, one is to solve the safety problem, the mining industry is a high-risk occupation, its drivers are more demanding and dangerous than the safety requirements of traditional passenger car drivers. Driverless can solve the safety problem, all the cars do not have a driver, miners do not go down the mine, zero casualties; Secondly, intelligent unmanned transportation, a key to start, automatic formation, efficient transportation. If the mine has 30-50 unmanned mining car, this time the background only need a computer scheduling can be, do not need people, but the remote scheduling room need to sit two people to play an auxiliary role in emergencies require human intervention; third is the intelligent system scheduling, intelligent planning transport routes, dynamic adjustment of the car shovel ratio, reduce the waiting time of the transport vehicle, improve loading efficiency; fourth is to save costs, the general driver's salary of a year to ten thousand, the driver is not a good idea. Someone car into an unmanned car, the driver's money can be saved back; five is the production process pollution-free, crack the environmental protection and inspection, such as "stop-work order".
④ Precise mapping and collaborative operations
5G drones and AI technology, timely access to ore reserves, accurate development of mining plans; collaborative tunneling machine, excavator, hydraulic bracket, mining trucks, and other equipment operations, to open up the data silos, to create a standardized, integrated and unified digital platform, to achieve the empowerment of mining applications, data ****. The company's business is to provide the best possible service to its customers.
Jinneng Holding Group Tashan coal mine, is the National Energy Administration ten million tons of intelligent mine construction pilot unit. Up to now, Tashan mine has completed the construction of four intelligent synthesized working face, the mine installed a total of 128 units of 5G base station, has realized the full coverage of the 5G signal up and down the well, which can support the remote control of underground synthesized mining equipment, tunneling machine, coal digger, hydraulic bracket, and other equipment through the 5G technology with a real-time remote control function, which can be made to realize the blasting, mining, transmission of the whole process of high-definition monitoring and control. The realization of the mine equipment remote operation and maintenance, "5G + intelligent coal mine" is beginning to take shape, the basic realization of the "machine into the people back" goal.
V Intelligent Mining Benefits?
Compared with traditional mines and smart mines, there are three main benefits, one is to save manpower, according to the annual mining of 10 million tons of mines, for example, the transport distance of 3 kilometers or less accounting, personnel to reduce to more than 50%, 5 years of labor cost savings of 6,560,000; the second is to enhance the efficiency of the single car autopilot to enhance to 30 kilometers / hour, the transport length of 24 hours from 16 hours up; The third is to increase efficiency, 5 years of direct revenue of 93.42 million, personnel casualties reduced to 0.
